Cemented Carbide Composition Containing Non-Strategic Metals as Blinders

摘要

Cemented carbides of the compositions 90 WC-10 Co, 90 WC-10 Ni and 90 WC-10 Fe were sinteredna)tConventionally at 2640°F (1450°C) for 90 minutes without the application of pressure during sinteringnBy passing an electric current through the samples and simultaneously applying pressure with sintering times between 10 and 14 cycles of 60 cycle current (10/60 to 14/60 of a second).
